Use the Image Mask template to create apps to calculate, visualize, and mask change between two images in an imagery layer. The template includes tools for measurement, recording locations, creating annotation, exporting imagery, and viewing changes over time.
For each image, app users have a choice from among these change detection modes:
- Difference Image: Calculates increases and decreases for the full extent.
- Difference Mask: Focuses on significant change by setting the minimum increase or decrease to be masked.
- Threshold Mask: Sets a threshold and magnitude for what is masked as change. The app only identifies change that's above the user-set lower threshold and magnitude.
